The competition must have been fierce in the sound editing category at the Oscars, because two movies won: Skyfall and Zero Dark Thirty.

It was only the sixth tie in Oscar history.

In 1968, Barbara Streisand (Funny Girl) and Katharine Hepburn (The Lion in Winter) tied for best actress. This is the only exact tie in academy history.

The first tie came in 1931-32, when Fredric March (Dr. Jekyll and Mr. Hyde) and Wallace Beery (The Champ) tied for best actor. They differed by one vote.

In 1949, A Chance to Live and So Much for So Little both won the best documentary short award.

In 1986, Artie Shaw: Time Is All You've Got and Down and Out in America were honored for best documentary, and Franz Kafka's It's a Wonderful Life and Trevor both won the best short film (live action) award.

If a nominee is three or fewer votes behind the winner, a tie is declared and the academy will award two Oscars, one to each nominee.

The winners tonight: From Skyfall, Per Hallberg and Karen Baker Landers, and Paul N.J. Ottosson for Zero Dark Thirty.

"Any time that you get involved in history-making, it's good, and also Paul is a friend of ours so that's nice," Hallberg said. Added Baker Landers: "And any time you win an Oscar, that's pretty OK."

Asked how she feels being the only woman winning in this category, Baker Landers said it's "really an honor to represent women in the industry and hang with the big boys. I hope I represent well."
